실험 절차

To a suspension of 0.09 g. (0.0024 mole) of 60% sodium hydride in 10 ml. of dry N,N-dimethylformamide is added dropwise over 5 minutes a solution of 0.5 g. (0.0024 mole) of 1-(3-hydroxybenzoyl)piperidine, prepared according to the method of G. Tilly, Chem. Ther. 2 (1), 57-65 (1967); C. A. 67 32432S, in 10 ml. of dry N,N-dimethylformamide. The mixture is stirred at room temperature for 5 minutes and then 0.64 g. (0.0024 mole) of N-(3-bromopropyl)phthalimide is added. The mixture is stirred at room temperature for 1 hour and is diluted with water to the cloudy point. The precipitate which forms is collected and is air dried to give 0.5 g. of product. A small amount is recrystallized from ethanol to give the analytical sample, m.p. 120°-122° C.
